Re: moving window handling into lisp

[Richard Stallman <rms@gnu.org>]

    Deleting windows currently is an inherent part of resizing, otherwise
    `window-min-height' and `window-min-width' wouldn't make sense.  Where
    and how would you handle these variables?

If window resizing is done in Lisp, the Lisp code could delete windows
whenever it wants to.  It could work using a low-level resize
primitive that would never delete windows.

This might require a primitive to undelete a window,
for the sake of dragging a boundary all the way across and back.
I'd guess that is not very hard to add.
